of which the following is a specification.

, The present invention relates in ,g ene ral to dumping vehicles, and more particularly vehicles of y a v 20"; are connected at one end to the' which to operating means for dumping the gravity dump type.

The object of the invention is toprovid e operating means for dumping vehicles of this character, which may be conveniently and easily controlled, either directly or remotely, which provides for the automatic righting-up of the dumping means and which is of simple and durable'construc tion, reliable in operation, and easy and inexpensive to manufacture.

Other objects and advantages reside in the certain novel features of the construction, combination and arrangement of'parts which will be hereinafter more fully described. and particularly pointed out in the appended claims, reference being hadto the accompanying drawings forming apart of this specification, and in which V Figure 1 is a plan view of the invention, with parts being broken away and shown in section for the sake ofillustration,

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention, the dumping Vehicle with which the invention is associated comprises a body designated at having gravity dump doors 11 pivotally connected to the lower end of the body. The body is arranged upon suitable ground wheels 12'bymeans of an axle 13. At the forward end of the body an extension 15 S p o dt and may be supported upon the draw+headi of a tractor or upon suitable running gear 1 if it is desired to use animal re windin- 'rshatt '16 is rotatably jour' nailed in" the extension 15 and has fixed thereto, preferably within the extension,

winding reels 17 and" 18; uponwhich re spec't'ively the" righting ap chain-s19 and 20 for the forward end of the dump doors, are

woundi Tlieseri-ghting-iip" chains 19' and ing drums arethen ledqoveri" suitable guide pulleys or sheaves designated at 2-1, to the forward end ofth'e dump doorsto which they are connected. Winding reels 22 and 23' are also fixed to the winding shaft, preferably exteriorlyr of the extension and upon thereels" 22: and 23, righting-up chains 24 and. 25 respectively are adapted! to" be wound. The chains are con nected: at one end to the reels and at the other end to connecting rodsr26; and 27, respectively slidably arranged in brackets 28and29, respectively, fi-xed'to the side of the-wagon body. The=connecting rods have theinr'ea'r endsconnected to adjacent" ends of chains 3O and.v 31, which are led over suitable guidexpulleys or sheaves 32=to be connected at their ends to the rear ends of the bottom dump doors.

A ratchet wheel 35 isfixedto the winding. shaft 16 within the eXtensiom-and is adapted to cooperate with apawl 36 pivotedto a bracket 37'mounted upon the extension 15. The" pawl 36:"isnormally operated upon by gravity to engage the ratchet wheel 35 and thus *niaintain. the winding shaft in set position. A releaselever", 38 is pivotally mounted at 39' upon v the bracket-:37 and is provided with a lifting toe- 40 engagcable withthepawl '36 to raise it out of engagement with the ratchet wheel 35. A retractile coil spring ll engages the lower end of the release le ver 38 and tends to maintain the same in' such position thatits lifting toe 45,0 will'not'engage the'p'awl 39. If a remote control is'used, a" flexible connecting element 42i'sfiXed'to the release lever and" extends to'the point of'control; I

.Actuati'ng means is provided for impart; in righting-up; movement to the winding shaft 16, and includes a pulley or winding sheave 45 fixed to the winding shaft 16 and adapted to receive the convolutions of a cord, cable or similar flexibleelement 46, one end of which is secured to the winding sheave and the other of which is secured as at 47 to the extension or other stationary part to form a loop 48. A pulley 49 is received in the bight of the loop 48 and is rotatably mounted at one end of a rod 50 which in turnis secured at its other end to a flexible element 51 preferably in the form of a chain. The flexible element 51 is led from the rod 50 over a guide pulley 52, and then downwardly under and around the axle of the vehicle or the hub of the adjacent wheel and upwardly on the opposite sideof the wheel to the anchor 53 to be hereinafter morefully described. The portion of the flexible element or chain 51 which extends from the pulley 52 to the anchor 53 constitutes a loop which is designated at 54. An inwardly extending projection designated at is provided on the ground wheel 12 adjacent the loop 54 of the flexible element 51, and is preferably in the form of a half spool as shown in the drawings, the single end plate or cheek of which has an inwardly inclined surface designated at 55. This projection or spool is mounted upon a base 56 which is adjustably secured in any suitable manner as by U-b0lts or the like, to the spokes of the wheel. It is apparent that the degree of movement imparted to the flexible element is controlled or determined by the distance at which the projection is spaced from the center of the wheel. As more clearly shown in dotted lines in Figure 3, the loop 54 normally hangs or lies in a plane spaced from the path of travel of the projection 55, so that normally when the reel revolves the projection 55 which of course is carried with the wheel and partakes of its motion, clears the loop and does not engage or in any wise affect the same.

A controller is provided for swinging the loop or a portion thereof into the pat-h of travel of the projection whereby the loop will be engaged and elongated by the pro jection. The controller includes a rotatable controller shaft 58 journaled in suitable bearings 59 and having at one end an operating lever 60 and at theother end adjacent the loop 54, a control bar 61 fixed thereto. The body of the controlbar 61 is provided with a slot 62 through which the chain of the loop 54 extends, and this body is oifset from the shaft 58 by means of a curved arm 63. It is obvious that when theoperating lever 60 is moved it will swing the body of the control bar in an arc and may be operated to swing it outwardly so that the loop 54 will be moved into the path of the projection 55. The bar 61 is arranged radially of the shaft 58 and its center of gravity is such that it operates to return the bar to normal position shown in dotted lines in Figure 3, at which position the loop lies out of the path of travel of the projection.

The anchor 53 for the chain or flexible ele ment 51, as shown in detail in Figure 5, comprises a base plate 65 secured to the wagon body to which a hook 66 is pivoted at 67. The hook 66 receives the end link and chain and the hook includes an arm 68 towhich is connected a. retractile coil spring 69 under tension and eflective to throw the hook. 66 in a direction opposite to the pull exerted by the chain 51. A pivoted release block 70 is also mounted upon the base plate and has a shoulder 71 which frictionally engages the top of the end link of the chain to prevent accidental displacement of the chain and to constitute a stop or abutment to limit the throw of the hook effected by the spring 69. It is obvious that when obstructions such as roots or the like are tangled in the dump doors and prevent closing of the same, the anchor operates to release the flexible element and thereby prevents the setting up in the component parts of the operating means destructive or injurious stresses.

In operation, when it is desired to effect righting-up of the dump doors, it being understood that the vehicle is advancing, the operator grasps the lever 60 and swings it so that the controlling bar will move the loo 54 of the flexible element into the pati of travel of the projection on the ground wheel which constitutes a movable element of the vehicle. As the ground wheel rotates, its projection 55 engages the loop 54 and elongates it. The elongation of the loop eflects a rearward movement of the rod 50, and this movement of the rod 50 by means of the pulley, 49 carriedin the bight of the flexible element 46, unwinds this flexible element from the winding sheave 45 and thus imparts rotary movement to the winding shaft. The rotary movement of the winding shaft effects the winding of the righting-up chains 19 and 20, and 24 and 25, upon their respective winding reels, and thus raises or closes the dump doors.

During this time, the pawl 39 and ratchet wheel 35 operate to maintain the winding shaft against reverse movement, and they also serve this function after the rightingup operation has been completed. In order to release the dump doors, it is merely necessary for the operator to move the release lever 38 which releases the pawl from engagementwith the ratchet wheel and permits the gravity dump doors to open.

It is to be noted that when the dump doors are in closed or righted-up position, the loop 54 of the flexible element 51 is elongated and hangs some distance below the same. If this is undesirable, slack may be secured at one end to the chain andat the opposite end to the wagon body.
